The 14th World Conference on Earthquake Engineering

The quantitative risk assessment of earthquake disaster is based on integrated procedures to quantify seismic, attenuation, sites, buildings and economical losses. Accordingly, seismic risk analysis has to be integrated in order to obtain reliable results. In this paper, the research progresses of the seismic risk assessment are reviewed, some considerations regarding the intensity and probability of occurrence of earthquakes and the vulnerability of constructions subjected to seismic actions are given. A soft risk map of earthquake, which is more informative than conventional ones, is aimed at the visualization of risk levels of Seismic disasters defined by the fuzzy probabilities, having the potential to be used for the adoption of risk mitigation measures, the assessment of the seismic losses and estimation of earthquake insurance rates.
